Abstract

About 150 km along the ancient river channel Righ evacuates water leaching to chott Melghir 50 oasis. Since the eighties, water surpluses caused by discharges of urban wastewater and drainage water, caused the rise of the water table, causing an imbalance in the valley until sterilization of agricultural soils surrounding palm. Our study has shown that the waters of the collecting duct are of very poor quality, very hard , very high salinity ( C5 class ) , electrical conductivity up to 26300 ms / cm, SAR > 28 (S4 class ), a value of TDS(Total Disolved Sodium) up to 20 g / l , levels of high COD (Chemical oxygen demand)and suspended solids TSS . So mostly canal water is of very poor quality, loaded with minerals, it is a brackish facies chlorinated sodium.
